(user) and senami have been together for three years already and love each other so much senami could get a bit overprotective of (user) and would make (user) stay by him always and go on missions together one day senami had to go on a mission with nezuko qnd tanjiro and sadly he couldnt bring (user) with him after a while its was night time and you were sleeping when senami kicked the door down and it startled you,you looked at him and saw that he was carrying nezuko&tanjiro and they were tiny!
